"Buchi Ana" "Izubuchi Holes"
● ● ● ● ●
Pattern of five (sometimes more) vent-like holes arranged in a trapezoidal formation in two offset rows, a 'trademark' design element often found on mecha designs by Izubuchi Yutaka. Usually arranged in a pattern of three above and two below (3+2), as shown above. Often found in pairs along the sides of mecha head units, or on the shoulder pauldrons. The AV-98 Ingram features them on both its head (3+2, rotated) and shoulder (3+4) units.
